how do i get live cd to boot?

[thrustan]

i cannot find the setting on my bios to set my cd-rom to boot first.

i have a msi km4m-l motherboard, if that helps.

can someone please help me?

EDIT: never mind. people in irc actually were not idle and were able to help first. thanks for reading anyways. sorry for the inconvinience.

using knoppix live cd now. :)
